Description
Technical Field
[0001] The utility model relates to the technical field of aerosol generating devices, in particular to an atomizing component and an aerosol generating device. Background Art
[0002] Some traditional aerosol generating devices use ceramics when manufacturing atomizer cores, but due to the poor structural setting and position of the ceramics, it is easy to cause poor airflow and poor taste when the user inhales. For example, in order to fix the ceramic atomizer core, the ceramic atomizer core is usually placed horizontally, and the fixed position of the ceramic atomizer core is located on both sides of the straight airway. However, in this solution, the horizontally placed ceramic atomizer core will block the straight airway in the aerosol generating device, causing the airflow in the airway to turn, affecting the taste. Utility Model Content
[0003] Based on this, it is necessary to provide an atomization assembly and an aerosol generating device to address the above problems.
[0004] An atomizing assembly, comprising:
[0005] A base, wherein the base is provided with a through hole along a thickness direction; and
[0006] A heating element is embedded in the hole wall of the through hole and enclosed with the hole wall of the through hole to form an atomization chamber.
[0007] Before describing the technical effects that can be achieved by the embodiments of the present application, it is necessary to explain that some traditional aerosol generating devices use a ceramic atomizer core and place the ceramic atomizer core horizontally in the vertical airway inside the aerosol generating device during assembly. Due to the obstruction of the horizontally placed atomizer core, the airflow needs to turn inside the aerosol generating device to pass over the atomizer core to take away the smoke generated on its surface. The structure is complex and easy to clog, the airflow is not smooth and concentrated enough, and the taste of the user when inhaling is poor.
[0008] In the face of the above-mentioned problems, the above-mentioned atomization assembly of the present application can at least achieve the following beneficial effects: the base of the atomization assembly can be installed in an aerosol generating device such as an aerosol generating device, and the thickness direction of the base can be considered to be roughly parallel to the vertical or axial direction of the aerosol generating device. The heating element is embedded in the hole wall of the through hole, and it can be considered that the heating element is placed vertically. Compared with the traditional scheme mentioned above, the structure of the atomization assembly is simpler. When the user uses the nozzle at the top of the aerosol generating device to inhale, the airflow can pass through the atomization chamber from bottom to top and flow through the surface of the heating element without turning. The airflow is not scattered and is more concentrated and smooth, so as to better carry away the aerosol generated on the surface of the heating element. The structure is simple and not easy to be blocked, and the TPM (Total Particulate Matter) value of the generated smoke is better, and the fullness of the smoke is better, which is beneficial to improve the taste performance of the smoke when it is inhaled by the user.
[0009] In one embodiment, the base has a first side and a second side that are arranged opposite to each other along the thickness direction, and the base forms a limiting column on the first side, and the through hole penetrates the limiting column along the axial direction of the limiting column, and a limiting notch is provided on the outer peripheral surface of the limiting column, and the limiting notch is connected to the through hole, and the heating element is embedded in the limiting notch and enclosed with the hole wall of the through hole to form an atomization chamber. Such a structural setting can be considered that the heating element is roughly embedded in the limiting notch on one side of the limiting column along the axial direction of the limiting column, that is, it can be considered that the heating element is placed vertically, and the side of the heating element exposed in the through hole can atomize the atomization medium to generate an aerosol that can be inhaled by the user. The setting of the limiting notch reserves space for the assembly of the heating element, which is convenient for assembly and automated production, and is conducive to improving assembly efficiency.
[0010] In one embodiment, the limiting notch passes through the end of the limiting column along the axial direction of the limiting column. Such a structural setting means that during installation, the heating element can be inserted into the limiting notch from top to bottom along the axial direction of the limiting column, which is more conducive to automated processing and processing consistency.
[0011] In one embodiment, the limiting notch has two side walls that are relatively spaced apart from each other, each of the side walls includes a first wall surface extending along the outer wall of the limiting column toward the through hole for a predetermined length, and a second wall surface extending along the inner wall of the limiting column toward the outer wall for a predetermined length, the first wall surface is connected to the second wall surface and is arranged at an angle; the heating element has an atomizing surface and two side surfaces respectively connected to both sides of the atomizing surface, the atomizing surface faces the through hole, one of the side surfaces abuts against one of the first wall surfaces, the other of the side surfaces abuts against another of the first wall surfaces, and both of the second wall surfaces abut against the atomizing surface. Such a structural setting can make the limiting column have a better clamping effect on the heating element. The two first walls are respectively abutted on the two side surfaces of the heating element, which can limit the axial movement of the heating element in the limiting column, and the two second walls are both abutted on the atomizing surface to limit the radial movement of the heating element in the limiting column. Because the two second walls can block the heating element in the radial direction of the through hole, the heating element is pressed by the two relative first walls and the second wall connected to the first wall. And because there is an angle between the first wall and the second wall, the heating element is subjected to a force toward the through hole, thereby preventing the heating element from escaping in the direction away from the through hole.
[0012] In one of the embodiments, at least a portion of the outer wall of the limiting column protrudes from a side of the heating element facing away from the through hole.
[0013] In one embodiment, the base is an elastic base, and the heating element is embedded in the limiting notch and elastically clamped by the side walls of the limiting notch. The base is elastic, so the limiting column and the two side walls at the limiting notch also have a certain margin of elastic deformation, which can reduce the manufacturing accuracy requirements of the heating element and other related parts and improve the connection reliability between the heating element and the base. It can be understood that even if the size of the heating element is slightly larger, the limiting column has a certain elasticity, and the heating element can still be embedded in the limiting notch and slightly enlarged. In other words, the limiting notch of the limiting column can not only flexibly adapt to heating elements within a certain size range, but also use the two side walls of the limiting notch to elastically clamp the heating element, thereby improving the connection reliability between the heating element and the base.
[0014] In one embodiment, the atomizer assembly further includes a circuit board and an electrode electrically connected to the circuit board, the circuit board is disposed on the second side of the base, and the electrode extends into the through hole and is connected to the heating element.
[0015] In one embodiment, the heating element includes a material guide body for conducting atomization medium and a heating wire embedded in the material guide body, and the heating wire is electrically connected to the electrode. The material guide body can contact with atomization medium such as cigarette oil to conduct the atomization medium into the atomization chamber, and the electrode supplies energy to the heating wire. When the heating wire is heated, the atomization medium in the material guide body is heated to be more easily atomized to form an aerosol.
[0016] In one embodiment, the material guide body is a sheet of ceramic.
[0017] In one embodiment, the electrode is in interference fit with at least part of the surface of the conductor. The electrode can not only be electrically connected to the heating wire in the heating element, but also can use its own structure to be in interference fit with at least part of the surface of the conductor to press the conductor tightly, thereby preventing the heating element from shifting toward the through hole.
[0018] In one embodiment, a ventilation groove is provided on one side of the material guide body facing the electrode, a portion of the ventilation groove is located between the electrode and the material guide body, and at least a portion of the ventilation groove extends outside the electrode. The atomized medium in the material guide body is conducted to the surface of the material guide body and atomized to form an aerosol, and the ventilation groove can timely discharge the bubbles accumulated therein to avoid affecting the subsequent generation of aerosol and prevent the bubbles from affecting the connection reliability between the electrode and the material guide body.
[0019] In one embodiment, the base is further provided with a snap-fitting protrusion on the second side, and the circuit board is provided with a snap-fitting recess, and the base is fixed to the circuit board through the snap-fitting recess and the snap-fitting protrusion. Such a structural setting is not only convenient for connecting and assembling the circuit board and the base, but also convenient for subsequent maintenance or disassembly of related parts for environmentally friendly recycling.
[0020] In one embodiment, the atomizer assembly further includes a sensor element, which is electrically connected to the circuit board and is used to detect changes in air pressure and drive the heating element to start working when the air pressure change is detected. The sensor element can be a microphone, etc., which can be used to detect changes in air pressure to determine whether the user has started to inhale.
[0021] In one embodiment, the electrode includes a fixing portion and an electrical connection portion connected to the fixing portion, the fixing portion is fixed to the circuit board and electrically connected to the circuit board, the electrical connection portion extends into the through hole and is electrically connected to the heating element, and the base is provided with a bayonet on the second side, the bayonet is used to abut against the fixing portion to limit the axial movement of the electrical connection portion in the through hole.
[0022] In one embodiment, the atomization assembly further includes an oil storage cotton, which is hollow inside and is sleeved on the outer peripheral surface of the limiting column and fits the heating element. The oil storage cotton can store atomization medium such as smoke oil, and the oil storage cotton fits the material guide body of the heating element to transfer the atomization medium into the material guide body.
[0023] In one embodiment, the outer peripheral surface of the base is provided with an oil blocking groove, and the atomizer assembly further includes a sleeve, which is sleeved on the outer peripheral surface of the base and covers the oil blocking groove. It can be understood that even if the atomized medium such as smoke oil has a tendency to seep out from the gap between the base and the sleeve, the oil blocking groove can still provide a certain space to store the atomized medium, preventing it from directly seeping into the shell and affecting the user's experience.
[0024] The present application also provides an aerosol generating device, which includes a shell and an atomizing assembly as described in any of the above embodiments, wherein the atomizing assembly is disposed in the shell.

Therefore, the aerosol generating device also includes at least the following beneficial effects: the base of the atomizing assembly can be installed in the aerosol generating device, and the thickness direction of the base can be considered to be roughly parallel to the vertical or axial direction of the aerosol generating device.

Compared with the traditional scheme mentioned above, the structure of the atomizing assembly is simpler. When the user uses the nozzle at the top of the aerosol generating device to inhale, the airflow can pass through the atomizing chamber from bottom to top and flow through the surface of the heating element without turning.

[0040] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

[0041] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the present application provides an atomization assembly 11, which includes a base 100 and a heating element 200. The base 100 is provided with a through hole 110 along the thickness direction, and the heating element 200 is embedded in the hole wall of the through hole 110 and enclosed with the hole wall of the through hole 110 to form an atomization chamber. It can be understood that in order to enable the heating element 200 to be enclosed with the hole wall of the through hole 110, the embedding can be considered that at least part of the contour of the heating element is connected to the hole wall of the through hole 110.
[0042] Before describing the technical effects that can be achieved by the embodiments of the present application, it is necessary to explain that some traditional aerosol generating devices use a ceramic atomizer core and place the ceramic atomizer core horizontally in the vertical airway inside the aerosol generating device during assembly. Due to the obstruction of the horizontally placed atomizer core, the airflow needs to turn inside the aerosol generating device to pass over the atomizer core to take away the smoke generated on its surface. The structure is complex and easy to clog, the airflow is not smooth and concentrated enough, and the taste of the user when inhaling is poor.
[0043] In the face of the above-mentioned problems, the above-mentioned atomization component 11 of the present application can at least achieve the following beneficial effects: the base 100 of the atomization component 11 can be installed in an aerosol generating device 10 such as an electronic cigarette, and the thickness direction of the base 100 can be considered to be roughly parallel to the vertical or axial direction of the aerosol generating device. The heating element 200 is embedded in the hole wall of the through hole 110, and it can be considered that the heating element 200 is placed vertically. Compared with the traditional scheme mentioned above, the structure of the atomization component 11 is simpler. When the user uses the suction nozzle 14 at the top of the aerosol generating device to inhale, the airflow can pass through the atomization cavity from bottom to top and flow through the surface of the heating element 200 without turning. The airflow is not scattered and is more concentrated and smooth, so as to better carry away the aerosol generated on the surface of the heating element 200. The structure is simple and not easy to be blocked, and the TPM (Total Particulate Matter) value of the generated smoke is better, and the fullness of the smoke is better, which is conducive to improving the taste performance of the smoke when it is inhaled by the user.
[0044] Specifically, Figure 2 and Figure 3 As shown, in some embodiments, the base 100 has a first side 101 and a second side 102 that are arranged opposite to each other along the thickness direction, and the base 100 forms a limiting column 120 on the first side 101, and the through hole 110 penetrates the limiting column 120 along the axial direction of the limiting column 120, and the outer peripheral surface of the limiting column 120 is provided with a limiting notch 121, and the limiting notch 121 is connected to the through hole 110, and the heating element 200 is embedded in the limiting notch 121 and enclosed with the hole wall of the through hole 110 to form an atomization chamber. Such a structural arrangement can be considered that the heating element 200 is roughly embedded in the limiting notch 121 on one side of the limiting column 120 along the axial direction of the limiting column 120, that is, it can be considered that the heating element 200 is placed vertically, and the side of the heating element 200 exposed in the through hole 110 can atomize the atomization medium to generate an aerosol that can be inhaled by the user. The setting of the limiting notch 121 reserves space for the assembly of the heating element 200, which is convenient for assembly and automated production and helps to improve assembly efficiency.
[0045] More specifically, if Figure 2 As shown, in some embodiments, the limiting notch runs through the end of the limiting column along the axial direction of the limiting column. Such a structural setting means that during installation, the heating element can be inserted into the limiting notch from top to bottom roughly along the axial direction of the limiting column, which is more conducive to automated processing and processing consistency.
[0046] More specifically, if Figure 7As shown, in some embodiments, the limiting notch 121 has two side walls 122 that are relatively spaced apart, each of the side walls 122 includes a first wall 1221 extending along the outer wall of the limiting column 120 toward the through hole 110 for a predetermined length, and a second wall 1222 extending along the inner wall of the limiting column 120 toward the outer wall for a predetermined length, the first wall 1221 is connected to the second wall 1222 and is arranged at an angle; the heating element 200 has an atomizing surface 201 and two side surfaces 202 respectively connected to both sides of the atomizing surface 201, the atomizing surface 201 faces the through hole 110, one of the side surfaces 202 abuts against one of the first wall surfaces 1221, the other of the side surfaces 202 abuts against the other of the first wall surfaces 1221, and both of the second wall surfaces 1222 abut against the atomizing surface 201. Such a structural setting can make the limiting column 120 have a better clamping effect on the heating element 200. The two first walls 1221 are respectively abutted on the two side surfaces 202 of the heating element 200, which can limit the axial movement of the heating element 200 on the limiting column 120, and the two second walls 1222 are both abutted on the atomizing surface 201 to limit the radial movement of the heating element 200 on the limiting column 120, so that the heating element 200 is pressed by the two relative first walls 1221 and the second wall 1222 connected to the first wall 1221, and due to the angle between the first wall 1221 and the second wall 1222, the heating element 200 is subjected to a force toward the through hole 110, thereby preventing the heating element 200 from escaping in the direction away from the through hole 110.
[0047] Furthermore, since the fixing of the heating element 200 can be completed by the limiting notch 121 set by the limiting column 120, in the present application, when the heating element 200 is made of ceramic material, a regular-shaped ceramic structure can be used to avoid the instability of the processing process caused by the use of a special-shaped ceramic structure. At the same time, considering that in some schemes, the outside of the atomizer core made of ceramic material needs to be wrapped with a layer of oil-conducting cotton to slow down the liquid-conducting speed, then the special-shaped ceramic atomizer core is not conducive to being wrapped with the ceramic atomizer core.
[0048] More specifically, if Figure 8 As shown, in some embodiments, the outer wall of the limiting column at least partially protrudes from a side of the heating element facing away from the through hole.
[0049] More specifically, if Figure 2As shown, in some embodiments, the base 100 is an elastic base, such as a base made of silicone material, and the heating element 200 is embedded in the limiting notch 121 and is elastically clamped by the side walls of the limiting notch 121. The base 100 is elastic, so the limiting column 120 and the two side walls at the limiting notch 121 also have a certain margin of elastic deformation, which can reduce the manufacturing accuracy requirements of the heating element 200 and other related parts and improve the connection reliability of the heating element 200 and the base 100. It can be understood that even if the size of the heating element 200 is slightly larger, since the limiting column 120 has a certain elasticity, the heating element 200 can still be embedded in the limiting notch 121 and slightly enlarged. In other words, the limiting notch 121 of the limiting column 120 can not only flexibly adapt to the heating element 200 within a certain size range, but also use the two side walls of the limiting notch 121 to elastically clamp the heating element 200, thereby improving the connection reliability of the heating element 200 and the base 100.

[0051] Specifically, in some embodiments, the heating element 200 includes a material guide body 210 for conducting an atomized medium and a heating wire (not shown) embedded in the material guide body 210, and the heating wire is electrically connected to the electrode 400. The material guide body 210 can contact an atomized medium such as cigarette oil to conduct the atomized medium into the atomization chamber, and the electrode 400 supplies energy to the heating wire, and the heating wire heats up, so that the atomized medium in the material guide body 210 is heated and more easily atomized to form an aerosol.
[0052] More specifically, in some embodiments, the material guide body 210 is a sheet-shaped ceramic.
[0053] More specifically, in some embodiments, the electrode 400 is interference fit with at least a portion of the surface of the conductor 210. The electrode 400 can not only be electrically connected to the heating wire in the heating element 200 to function, but the electrode 400 can also use its own structure to be interference fit with at least a portion of the surface of the conductor 210 to press the conductor 210 tightly, thereby preventing the heating element from shifting toward the through hole 110.
[0054] Furthermore, if Figure 4As shown, in some embodiments, a ventilation groove 211 is provided on one side of the material guide body 210 facing the electrode 400, a portion of the ventilation groove 211 is located between the electrode 400 and the material guide body 210, and at least a portion of the ventilation groove 211 extends outside the electrode 400, that is, a portion of the ventilation groove 211 is located outside the contact position between the electrode 400 and the material guide body 210. The atomized medium in the material guide body 210 is conducted to the surface of the material guide body 210 and atomized to form an aerosol, and the ventilation groove 211 can timely discharge the bubbles accumulated therein to avoid affecting the subsequent generation of aerosols and prevent the bubbles from affecting the connection reliability between the electrode 400 and the material guide body 210.
[0055] Furthermore, if Figure 3 and Figure 5 As shown, in some embodiments, the electrode 400 includes a fixing portion 410 and an electrical connection portion 420 connected to the fixing portion 410, wherein Figure 3 and Figure 5 In the illustrated embodiment, the cross-sectional profile of the fixing portion 410 of the electrode 400 is substantially circular, that is, the fixing portion 410 of the electrode 400 is substantially cylindrical, the electrode 400 portion is connected to the end surface of the fixing portion 410, and the cross-sectional profile of the electrode 400 portion is arcuate. The fixing portion 410 is fixed to the circuit board 300 and electrically connected to the circuit board 300, the electrical connection portion 420 extends into the through hole 110 and is electrically connected to the heating wire, and the base 100 is provided with a bayonet 150 on the second side 102, and the bayonet 150 is used to abut against the fixing portion 410 to limit the movement of the electrical connection portion 420 in the axial direction of the through hole 110.
[0056] See also Figure 3 In some embodiments, the base 100 is further provided with a snap-fitting protrusion 130 on the second side 102, and the circuit board 300 is provided with a snap-fitting recess 310, and the base 100 is fixed to the circuit board 300 through the snap-fitting recess 310 and the snap-fitting protrusion 130. Such a structural setting is not only convenient for connecting and assembling the circuit board 300 and the base 100, but also convenient for disassembly during subsequent maintenance or disassembly of related parts for environmentally friendly recycling.
[0057] See also Figure 1 , Figure 4 and Figure 5In some embodiments, the atomizer assembly 11 further includes a sensor element 700, and the atomizer assembly 11 further includes a bracket 500, which is disposed between the sensor element 700 and the base 100. The sensor element 700 is electrically connected to the circuit board 300 and is used to detect air pressure changes and drive the heating element 200 to start working when air pressure changes are detected. The sensor element 700 can be a microphone, etc., which can be used to detect air pressure changes to determine whether the user has performed a puffing operation.
[0058] See also Figure 1 In some embodiments, the atomizer assembly 11 further includes an oil storage cotton 800, which is hollow inside and is sleeved on the outer peripheral surface of the limiting column 120 and fits with the heating element 200. The oil storage cotton 800 can store atomizing medium such as smoke oil, and the oil storage cotton 800 fits with the guide body 210 of the heating element 200 to transfer the atomizing medium into the guide body 210.
[0059] See also Figure 1 In some embodiments, the outer peripheral surface of the base 100 is provided with an oil blocking groove 140, and the atomizer assembly 11 further includes a sleeve 600, which is sleeved on the outer peripheral surface of the base 100 and covers the oil blocking groove 140. It can be understood that even if the atomized medium such as smoke oil has a tendency to seep out from the gap between the base 100 and the sleeve 600, the oil blocking groove 140 can still provide a certain space to store these atomized media, preventing them from directly seeping into the housing and affecting the user's experience.
[0060] In addition, if Figure 1 As shown, the present application also provides an aerosol generating device 10, which includes a shell 13, a nozzle 14 and an atomizing assembly 11 as described in any of the above embodiments, wherein the atomizing assembly 11 is disposed in the shell 13, and the nozzle 14 is covered to the top of the shell 13 and is connected to the atomizing chamber for a user to inhale aerosol therefrom.
